I am have listed a golf club for sale and am new to Ebay selling.  I had Ebay select package size and I never changed it from the standard small package/ envelope through USPS Priority Mail.  This will obviously require more than a small package.  What are my options when this item eventually sells?  

I appreciate the answers all of you!  I have changed the shipping on one of my listings to reflect this, but the other had bids and I didn't want to end it.  I will just let it run out and I'll pay the extra if any and chalk this up as a learning experience!  

Thanks!
